As a cage is full of birds,.... Jarchi and Kimchi understand it of a place in which fowls, are brought up and fattened, what we call a "pen"; and, so the Targum renders it, a house or place of fattening.
The word is rendered a "basket" in Am 8:1 and may here design one in which birds taken in snares, or by hawking, were put. The Septuagint version, and those that follow it, render it, "a snare": which agrees with what goes before.
